Patented 001.25, 191`o salt to maintain the brine at a high degree of concentration. The pump g is preferably detachably connected with thecrank-arm so that it may'bedis'connected Whenever de# sired. Said pump gserves as an independent means for conducting brine from the tank to the salt-receptacle.

Referring-to. Fig.' 2, similar independent lileans for conducting a'-relativ'ely small quantity of brine to the salt is shown, but in this instance the salt is contained in bags which are forarninous and rests on the pieces of ice, and the return pipe a3 extends down into the tank at-one end.

' Referring to Fig. 3 a modified means for conducting brine to the :salt-receptacle gB is shown, wherein a chain pump h is employed of any well 'known or suitable construction, which is larranged within the tank and extended' down into the brine in said tank, and is adapted'toconduct the brine from the tank to the salt-receptacle. Said chain pump may-be operated by a rotary motor/t" of any suitable construction arranged to be operated by the force of the brine returning from the circulation pipes, and which is under some pressure by the action of the pump b'. Said modified means however merely illustrates another independent` means which-may bel emplo ed for carrying out this-invention,

'where )y only a relatively small quantity of 1 brine'is'conducted to the. salt-receptac A tial-ly as' described.
